Row access support

[tvar]

Support for accessing elements of row type.
Like this:
SELECT (t.tup).id, (tup).name FROM t
https://www.postgresql.org/docs/current/rowtypes.html#ROWTYPES-ACCESSING

Additionally remove in LEFT expression because it's just case of ROW-construct
without this fix doesn't work queries like this:
(t.tup).id IN (1, 2, 3)

Coverage decreased (-0.003%) to 88.791% when pulling 6908aff on tvar:row_access_support into 8eb3d9a on JSQLParser:master.

Wasn't this already solved in the actual snapshot 4.1?

No, I've get current master and add my test case

    @Test
    public void testSelectRowElement() throws JSQLParserException {
        assertSqlCanBeParsedAndDeparsed("SELECT (t.tup).id, (tup).name FROM t WHERE (t.tup).id IN (1, 2, 3)");
    }

It failed. I can't see any code to support access tuple elements.

Then sorry. I merged.
